Abstract

Even when an OSD video signal is superimposed on a video signal, deterioration in the frequency characteristic or in gradation of the video or OSD video signal superimposed on it is minimized. A graphic image is represented by a video signal that provides color information and degree of transparency information on a pixel basis. The video processor includes: a filtering section, which receives and converts a 4:2:0 format video signal representing the video into a 4:2:2 or 4:4:4 format video signal; a decision section, which determines, by reference to the transparency information, whether the graphic image be superimposed on the video; a synthesizing section, which superimposes a color difference signal representing the graphic image on that of the video signal converted by the filtering section; and a scaling section for performing scaling on the synthetic color difference signal. Depending on the decision result, the filtering and scaling sections change between a mode of processing to retain pixel data and location information of the color difference signal of the 4:2:0 format video signal and another mode of processing to retain not to retain the pixel data and location information.
